The 20-year-old striker scored one goal, against Tranmere Rovers in a 2-1 vicory, in his five appearances for the Nationwide Division Two side.
Tangerines manager Steve McMahon had been hoping to keep Johnson for a second month but following talks the player has decided to return to Elland Road.
Johnson has played in four Premiership games for Leeds and had a successful loan spell with Hull City last season.
